SPECIFICATION forming part of Letters Patent No. 709,256, datedseptember 16, 1902.

Application led .Tune 7, 1901. Serial No. 63.495. 'KNO model.)

To all whom. it may concern.-

Be it known that LEDMUND HANDEL BUTTS,

a citizen of the United States, residing at Obey ron, in the county ofBenson and State of North Dakota, have invented certain new and usefulImprovements in Drags or Harrows; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in harrows, and especially to theclass of harrows often termed drags The objects and the special featuresof the invention will be fully pointed out in the specification andclaims below.

In the accompanying drawings, Figure lis a top or plan view of mycomplete drag or harrow. Fig. 2 is a sectional side elevation on theline ct ct in Fig. 1 with the yoke 2 and right-hand shaft 14 and itslever 20 omitted. Fig. 3 is a side view of one of the braces 3:3 inFig. 1. Fig. 4 is a partly-sectional View about as on the line b b inFig. 1.

Referring to the drawings by reference-numerals, 1 is the draft-bar andis provided with the yoke or'large clevis 2 for bitching a team to. Tothe center of this draft-bar is bolted at 3 'the upwardly and rearwardlyextending frame-bar 4, which at its front angle is strengthened by thebrace, while under its rear part is pivotally secured at 6 ahorizontally-swinging arm or short tongue 7, at the rear end of which issecured the axle 8, carried by the ground-wheels 9.

Near the middle of the frame-bar 4 is secured at each side of it aserrated sector-plate 10, in which there is a vertical slot l1, (seeFigs. 2 and 4,) enlarged at its upper end 12 to permit the insertion ofthe head 13 of the shaftl4, which has a neck l5, adapted to rest in thelower and narrow end of the slot as its j ournal-box, while the outerend of the shafts 14 are carried by the ground-wheels 16. I prefer toform said shafts 14 and the heads 13 in the manner shown in Fig. 4--thatis, 14 is a tube having secured in it by the piu 18 a cast or malleableplug 17, on which is formed integrally the neck 15, head 13, and arm 19,to which is secured the lever 20 with t-he latch 21, rod 22, and slidingdog 23, adapted to interlock with the serrations in the sector 10.

Upon the two shafts 14 are adjustably secured by the set-screws 24 thecollars 25, having horizontal arms 26, connected by chains or links 27tofthe side sections 28 of the drag, which sections are also secured tothe draftbar 1 b v the links 30. Similar links 30X connect with thedraft-bar the middle section 29 of the drag. The latter section issuspended by the links 27X and arms 26X, adjustably held by set-screwson the rock-shaft 14X, journaled in the front ends of the sector-platesl0 and carrying a hand-lever 20X, havinga latchoperated dog, the same asthe lever 2D in Fig. 4, engaging a serrated sector 10X, secured on theframe-bar 4 forward of the shafts 14.

31 represents diagonal braces from the frame-bar to the draft-bar, and32 represents longitudinal braces secured to the draft-bar by bolts andthu mb-nuts 33 withtheir front ends and having their rear ends journaledon the shafts 14, preferably by simply being hooked over the shaftbetween the collars 34. The braces 31 and 32 are offset upwardly, as at35 in Figs. 2 and 3, to permit the sections of the harrow to be elevatedby the arms 26 26X and shafts 14 and 14X and hand-levers 20 20 when sodesired in transportation of the harrow or in releasing each sectionfrom obstructions of any kind.

In further alluding to the use of this drag or harrow it will beunderstood that the collars 25 25 may be moved to any desired places onthe shafts,and thus permit the links 2727 to be connected toharrow-sections of various sizes and types, and that the dividing of theshaft 14 14 into three sections, each provided with a hand-lever andadjacent lockingsector, enables the operator to raise each section ofthe harrow independently of the other sections.

In Fig. 2, 36 designates barrow-teeth, the shape and size and number ofwhich may be varied as desired, as may also be the rockshafts with theirlevers and the sections of the harrow itself. 37 is a drivers seatsupported by the spring-arm 38, secured to the frame-bar 4. Having thusdescribed my invention,what

IOO

I claim, and desire to secure by Letters Patent, is-

1. A harrow comprising in combination, a

. series of barrow-sections adapted to be drawn side by side, adraft-bar link-fastened tothe front ends of all the sections, aframe-bar secured with its front end to the middle of the draft-bar andextending upwardly and rearwardly over and beyond the barrow-sections, adrivers seat secured on the frame-bar, a horizontally-swinging armpivoted under the rear part ofthe frame-bar and having a transverselydisposed short shaft with carrier- Wheels at its ends; the serratedsectors l0, secured at both sides of the frame-bar, rockshafts 14cextending transversely out from hoth sides of the frame-bar, near thesectorplates and journaled central with the latter,

Yand carrying levers having latch-operated dogs adapted to engage theserrations of the sectors,ground-Wheels 16 supporting the outer ends ofthe shafts 14:, and adjustable arms, 2b', link-fastened to thebarrow-sections, and the braces 32 between the draft-bar and the shafts14:, substantially as and for the purpose set forth.

2. A hai-row having a longitudinally-disposed elongated supporting-framewith a horizontally-swinging arm pivoted With its front end under therear end of the frame, and provided at its rear end with a short axlehaving two ground-wheels traveling behind the harrow-sections.

3. In a hal-row, the combination with a supporting-frame having thesector-plates 10 with serrations and each with a central vertical slotenlarged at its upper end, 0f the side shaft 14 having the neck 15 andhead 13 and latchlever with dog adapt-ed to engage the serrations of thesector when the neck of the shaft is journaled in the narrow bottom endof the slot, and Wheels supporting the outer ends of the shafts.

4. A harroW-frame having side bearings for side shafts to extend inopposite directions from the frame, and shafts journaled each with oneend in such bearings, said journals consisting of an annular grooveformed near the end of the shaft, and said bearing consisting of a platehaving a vertically-elongated hole enlarged at its upper end for theinsertion of the end of the shaft till its neck can be placed in thenarrow betteln end of the slot which serves as its bearing.

In testimony whereof I a'ix my signature in presence of two witnesses.

EDMUND RANDEL BUTTS.
